What is meant by the phrase 'In Jesus' Name' or 'In the name of Jesus'?

Answer 1

This expression is used because it is believed that there is power in the name of Jesus. When someone invokes this name it is usually in a preyer and the person using it is not only trying to identify with the God they are preying to but also trying to put as much power behind it as they can. Jesus also told his followers to cast out demons in his name. Jesus said anyone who mentions my name here on Earth I will mention that person to my Father in Heaven. He also said ask anything in my name and I will do it. Another reason is that people pray in His name, so since He sits at the right hand side of the God head...... It was common for someone to request something and call upon the name of an authority. They may said I beseech you in the name of Casear. Jesus said there was no higher authority than God. Later, Jesus rose from the grave and defeated the Devil. The scripture then said his Name is above all authority in heaven and on earth. So if you want to declare or request something, there is no higher authority that you can call upon.

Answer 2

The name Jesus is a transliteration of the Hebrew "Joshua" (which is why you find Him occasionally referred to as Yeshua by people of Jewish background who have become Christians).

The Hebrew word Joshua means 'Jehovah is salvation', hence the meaning of Jesus name savior.

Matthew 1:21 (King James Version)21And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.

The meaning of His name is also clear from the purpose for which He came,

the purpose of which He was Himself aware and which He carried out on the cross of Calvary and sealed with the glorious resurrection.

Jesus is the anglicised form of Jeshua, 'The Lord is salvation.'

Another answerThe name Jesus is meaningless because it is a transliteration and not an actual translation. To translate a meaning into Greek from the original Hebrew name of the Messiah, Yahshua, it would translate to Theosateria, meaning god (theos) is salvation (sateria). The problem with transliterations are the fact that they are a letter for letter and sound for sound conversion from one language to another. Because the original Hebrew Name Yahshua has a specific meaning tied to His purpose, the Greek transliteration has no meaning what so ever. A true meaning for meaning translation of the Hebrew born, Hebrew named, Hebrew raised, Hebrew buried Messiah Yahshua would be Theosateria in the Greek/English. Since people don't change their name depending on the country they travel to, there is no reason to change the name of the Messiah. If Jesus is the translation of Joshua, then the book of Joshua that appears in The Bible should also be called Jesus.
